I have several Silkolene Comp4 Semi-synthetic 10W-40 quarts for 02YZ426 and hate to have it just eyeballing me while I have no opportunity to get to a mx shop before tomorrow. I have always used Silkolene Medium Gear Oil SAE 85/90 in my 96 KX250...I am sure this is a novice question...but what difference would it make if I used a quart of 4-stroke lube in the KX? I do not want to mess anything up but it just seems like having something in the tranny would beat the spooge in there now. Tried to search this one but did not find anything that addresses my crossover concern. Also, is there anything over the counter I can nab at an automotive parts house for a 2-stroke?
